Notes from today’s meeting:

@joemcgill #59532 was fixed last week and some unit test improvements were added thanks to @thekt12
@thekt12 Working on implementing caching using transient for non-persistant cache website #59719 I have drafted an initial PR for just block pattern PR – https://github.com/WordPress/wordpress-develop/pull/6137
@joemcgill The past couple weeks, I’ve been mostly profiling the 6.5 betas against 6.4.3 to see why were are seeing a net server-timing regression in spite of the improvements we’ve made. So far, I haven’t found a clear cause or opportunity to avoid the regression but am continuing to look. More eyes would be helpful for sure.
@spacedmonkey There are 1020 matches for register_block_pattern in the plugin repo – https://wpdirectory.net/search/01HQNNQ2VPN4CKBQYKCQEC7Y87

Notes from today’s meeting:

@flixos90 I’m planning to get back to looking at the PR for #42441 later this week

Projects from the 2024 roadmap:

- Interactivity API
- Speculative prerendering
- Embed Optimizer

Notes from today’s meeting:

@westonruter the Embed Optimizer is ready for initial submission to the directory
@thelovekesh Web Worker offloading aka Partytown module is ready for final review. Since INP date is coming soon and it provides a good opportunity to offload 3P scripts, I think we can move forward with it

@thelovekesh Aside, I have started a discussion on improving the DX in new monorepo setup – https://github.com/WordPress/performance/issues/1012
- While working on a POC for this, I found out some issues with wp-env based tests setup. I have explained them on – https://github.com/WordPress/performance/pull/1013

@pbearne I have been working on the old core performance tickets. Clearing out won’t fix and refreshing the code as needed. if anybody wants me to jump to a later ticket, ping me
@johnbillion What’s the process for adding the [Focus] ... label to an issue? Is that for categorisation or only for issues that are an active focus for each team?
- @flixos90 It’s categorization primarily. We have never had anything (at least as far as I remember) that didn’t fit in one of the existing focus groups
- @joemcgill I believe that they used to align to the original project boards that were set up on the repo, which have evolved over the past few years, so they probably need a refresh at some point. Currently, I agree we’re not really using them for any reason
